前言目的 描述
肝腺瘤的超声（US）、CT和MRI表现与病理基础,探讨综合影像对肝腺瘤的诊断价值。方法 回顾性分析经手术切除、病理证实的6例肝腺瘤的US、CT和MRI表现,并与病理所见对照。结果6例肝腺瘤均为单发肿块,1例术前综合影像诊断为肝腺瘤,4例误诊为
肝癌,1例误诊为肝局灶
结节性增生。US:6例呈稍低或低回声,4例有低回声晕,彩色多普勒显示6例肿块内有较丰富的门脉样血流和低速动脉样血流。CT:6例为稍低或低密度,4例有假包膜,4例动脉期、门脉期均轻度强化,1例动脉期中度强化、门脉期轻度强化。MRI:T1WI和T2WI上,6例表现为以高信号为主的混杂信号,用脂肪抑制后T1WI上的高信号无变化;2例动脉期显著强化、门脉期和延迟期轻度强化,3例动脉期、门脉期和延迟期均轻度强化。6例均有假包膜,且在门脉期或延迟期出现轻度强化。结论 肝腺瘤的综合影像表现缺乏特异性。对有假包膜和混杂高信号（用脂肪抑制后T1WI上的高信号无变化）的多血供肿块应考虑到肝腺瘤的诊断
